Versatile saddle assy has multiple standard bolt patterns to accommodate different mounts. Comes with matching dove tail plate that is also predrilled to match a variety of scopes. This universal system will fit Losmandy GM8 and G11 mounts as well as certain Meade, Vixen and others. This is a well made heavy duty black annodized aluminum saddle assy of unusual and useful design. Perfect for someone who needs saddle and matching mounting plate for custom mount. I will post a photo tonight. Sell for $70 obo. Many thanks for consideration!
